Description

Technical Field

[0001] The invention belongs to the technical field of transporting and loading long steel rails, and in particular relates to a system and method for jointly alleviating unbalanced weight of a long steel rail transporting and loading vehicle group. Background Art

[0002] When a long rail car set is running, due to braking or longitudinal impulse between vehicles, the buffer will be compressed or stretched, which will cause the length of the load-bearing rails on the safety car to change, and the weight will change accordingly; when one end of the safety car is loaded with rails, the weight will be greater than the other end, and a longitudinal weight imbalance problem will occur. The current solution to the weight imbalance problem is to add counterweights at the other end, but the method of alleviating the weight imbalance by only adding counterweights is too simple and the relief strength is limited. When the car set carries some old rails in poor condition, the rail head will be tilted or deflected, which will cause a significant change in the weight of the load-bearing rails and make the weight imbalance more serious. Therefore, the weight imbalance alleviation strength is insufficient, and the weight imbalance value of the safety car exceeds the railway limit. Summary of the invention

[0003] The present invention aims to provide a system and method for alleviating overweight of a long rail transport and loading vehicle set, which can alleviate the overweight of a safety vehicle set in many aspects, and solve the problem that the overweight method of alleviating the overweight by adding counterweight blocks is too simple and the overweight alleviating force is insufficient, resulting in the overweight value of the safety vehicle exceeding the railway limit.

[0004] To this end, the technical solution adopted by the present invention is: a long rail transport and loading car group combined with weight imbalance alleviation system, including a safety car group, a locking car group and a rail transport car group, the safety car group is organized at both ends and consists of a front safety car and a rear safety car, each rail transport car of the rail transport car group is equipped with a roller beam, the front part of the front safety car is equipped with a roller beam, the front part and the middle part of the rear safety car are equipped with roller beams, the height of each layer of roller beams of the front safety car is lower than the roller beams of the corresponding layer of the rail transport car group, so that the hoisted rails fall on the rail transport car group first to alleviate the early weight imbalance of the front safety car, and the middle part of the rear safety car The height of each layer of roller beams is higher than that of the corresponding layer of roller beams in the front, and the height of each layer of roller beams in the front is consistent with the height of the corresponding layer of roller beams on the rail transport vehicle, so that the hoisted rails fall on the middle roller beams of the rear safety vehicle first to alleviate the early weight imbalance of the rear safety vehicle; the front safety vehicle is equipped with a movable counterweight device, and the moving range is from the front of the front safety vehicle to the middle of the front safety vehicle, fixed counterweight steel frames are installed at the two corners of the rear of the front safety vehicle, and a fixed counterweight steel block is installed above the rear safety door of the rear safety vehicle, and the rear safety vehicle is equipped with a movable counterweight device, and the moving range is from the middle of the rear safety vehicle to the rear of the rear safety vehicle.

[0005] As a preferred embodiment of the above scheme, the mobile counterweight device includes a counterweight block, a counterweight block track, a counterweight lock symmetrically arranged on the outside of the counterweight block track, and a counterweight block moving group arranged at intervals on the left and right for manually moving the counterweight block. The counterweight block is easy to move, has a stable structure, and is firmly installed. The four corners of the bottom of the counterweight block are provided with rollers that move along the counterweight block track, and counterweight locking ports symmetrically arranged on the left and right edges. When the counterweight block moves to the end of the counterweight block track, it can be fixed by the counterweight lock being inserted into the counterweight locking port. The design is reasonable, and it is easy to install and maintain, and the cost is low.

[0006] Further preferably, the counterweight lock includes a fixed seat and a baffle rotatably mounted on the fixed seat, the fixed seat is provided with an anti-jump pin hole, and is equipped with an anti-jump pin parallel to the baffle rotating shaft, the anti-jump pin is located below the baffle, when the counterweight block moves to the end of the counterweight block track, the baffle rotates to a horizontal state and snaps into the counterweight locking mouth, and the anti-jump pin can further limit the rotation angle of the baffle. The design is exquisite, the anti-jump pin can effectively prevent the baffle from jumping out of the counterweight locking mouth due to the vibration of the vehicle operation, the end of the anti-jump pin is provided with an anti-drop ring to prevent the anti-jump pin from falling off due to the vibration of the vehicle, the structure is interlocking, and the design is reasonable.

[0007] Further preferably, the left and right edges of the counterweight block are symmetrically provided with safety locking holes, and the outer side of the counterweight block track is provided with a safety lock matching the safety locking hole, which can be used as a substitute in case the counterweight lock fails, effectively avoiding the situation where the counterweight block cannot be fixed.

[0008] Further preferably, the counterweight block moving group uses horizontal iron bars of equal length set at intervals, and is equipped with a crowbar that uses the iron bars as a fulcrum to pry the counterweight block to move. Prying is convenient and labor-saving. Since the moving is random, the distance that the counterweight block can slide is not fixed when it is moved. Therefore, the iron bars are set at intervals to facilitate flexible moving.

[0009] It is further preferred that the height of each layer of roller beams of the front safety car is 8mm to 15mm lower than the roller beams of the corresponding layer of the rail transport car set, and the height of each layer of roller beams in the middle part of the rear safety car is 8mm to 15mm higher than the roller beams of the corresponding layer in the front part. The height difference is reasonable, and the rails will not be tilted due to excessive height difference. In the initial stage of the hoisting rails, the weight of the rails borne by the ends of the safety car is reduced, which can effectively alleviate the unbalanced weight of the front and rear safety cars.

[0010] The present invention also adopts a technical solution: a method for alleviating unbalanced weight of a safety car of a long rail transport vehicle group, comprising the following steps:

[0011] Step S1, adopting the above-mentioned long rail transport and loading vehicle group joint weight relief system, and when the vehicle is newly manufactured, adjusting the height of each layer of the rolling track beam of the front safety vehicle to be lower than the rolling track beam of the corresponding layer of the rail transport vehicle group, and adjusting the height of each layer of the rolling track beam in the middle of the rear safety vehicle to be higher than the rolling track beam of the corresponding layer of the front;

[0012] Step S2, setting up empty parking spaces and heavy parking spaces at both ends of the counterweight track, respectively, the empty parking space of the front safety car is adjacent to the front rolling beam, and the heavy parking space is located in the middle of the front safety car, the empty parking space of the rear safety car is connected to the middle rolling beam, and the heavy parking space is located directly below the rear safety door, and then the counterweight is moved to the empty parking space before loading the rails;

[0013] Step S3, start loading rails, and when the vehicle is empty or loaded with one or two layers of rails, the counterweight block stays and is fixed at the empty parking space; when loading three layers of rails, the counterweight block stays and is fixed at the empty parking space or the heavy parking space; when loading four layers of rails, the counterweight block is pre-fixed at the heavy parking space.

[0014] Beneficial effects of the present invention:

[0015] (1) By changing the height of the corresponding layer of the rolling beam of the safety car group, a height difference is formed, so that the hoisted rails fall on the rail transport car group first to alleviate the early overweight situation of the front safety car, and the hoisted rails fall on the middle rolling beam of the rear safety car first to alleviate the early overweight situation of the rear safety car. In the early stage of the hoisting rails, the weight of the rails borne by the end of the safety car group is reduced. The design concept is ingenious and can alleviate the overweight situation of the safety car group in the early stage of hoisting rails.

[0016] (2) A mobile counterweight device with a moving range from the front to the middle is installed on the front safety car. The moving range is reasonable. Fixed counterweight steel frames are installed at the two corners of the rear of the front safety car. Considering that the roller beam of the front safety car is at the front end and too far away from the adjacent rail transport car, the center of gravity of the front safety car when loading rails is at the front end. The mobile counterweight device needs to be moved to the middle and the center of gravity is adjusted with the help of the fixed counterweight steel frame at the rear to realize the combination of fixed and mobile counterweights, so as to balance the center of gravity of the front safety car when installing rails. The overall counterweight structure is reasonably arranged, which effectively avoids the occurrence of unbalanced weight of the front safety car.

[0017] (3) A fixed counterweight steel block is installed above the rear safety door of the rear safety car, and a mobile counterweight device with a moving range from the middle to the rear is installed on the rear safety car. The moving range is reasonable. The roller beam of the rear safety car is located in the middle and front. Therefore, the center of gravity of the rear safety car after loading the rails is in the middle and front. Therefore, it is necessary to install a fixed counterweight steel block on the rear safety door for balance, and install a mobile counterweight device for flexible weighting. The fixed counterweight structure and the mobile counterweight structure are cleverly combined to achieve the overall center of gravity balance of the rear safety car, effectively avoiding the occurrence of unbalanced weight of the rear safety car.

[0018] (4) Multiple methods are used to alleviate the overweight situation of the safety train. The overweight situation of the safety train is alleviated by adjusting the height of the rolling beam of the safety train and combining mobile counterweights with fixed counterweights. The overweight situation can be alleviated from the early stage to the late stage of rail loading. The overweight situation is alleviated with great strength and wide range, effectively avoiding the situation where the overweight value of the safety train exceeds the railway limit.

[0019] (5) Empty parking spaces and loaded parking spaces are set up at both ends of the counterweight track. The empty parking space of the front safety car is adjacent to the front rolling beam, and the loaded parking space is located in the middle of the front safety car. The empty parking space of the rear safety car is connected to the middle rolling beam, and the loaded parking space is located directly below the rear safety door. Based on the actual situation, the empty parking space and loaded parking space are set up accurately, which can effectively adjust the center of gravity of the safety car group and improve the safety of vehicle operation.

[0020] (6) When the vehicle is empty or loaded with one or two layers of rails, the counterweight block stays and is fixed in the empty parking space. When loading three layers of rails, the counterweight block stays and is fixed in the empty parking space or the loaded parking space. When loading four layers of rails, the counterweight block is fixed in the loaded parking space in advance to ensure that when loading the first three layers of rails, only the height difference of the corresponding layers of the rolling beam and the fixed counterweight are needed to balance the center of gravity of the safety vehicle group and alleviate the unbalanced weight. When loading the fourth layer of rails in the later stage, it is clearly necessary to use the mobile counterweight for adjustment to ensure that the unbalanced weight value after adjustment has a large margin, a large force to alleviate the unbalanced weight, and strong practicality.

[0021] To sum up, it has the advantages of multi-mode linkage relief, strong weight relief, high vehicle operation safety and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
